Reviving a Transplanted Hosta

Hostas can take several years to reach their full size.

Hosta, also known as plantain lily or funkia, is a shade-loving perennial plant grown for its attractive leaves. Hostas thrive in U.S. Department of Agriculture Zones 3 through 8, and although the roots are very hardy, foliage dies back to the ground at 28 degrees Fahrenheit. Spring and summer are the best times to transplant hostas. Summer-transplanted hostas usually remain dormant for one growing season before resuming active foliage growth. Giving hostas the water, sun and fertilizer they need will encourage healthy root development and a lush display of leaves.

Water

Most varieties of hosta need at least 50 to 60 inches of water per year to thrive, although mature hostas can survive drought-like conditions. Immediately after transplanting, water enough to settle the soil and remove air pockets around the plants. Watering is best done at the soil level with a drip irrigation system, as wet hosta leaves can develop fungal disease. When kept dry, the leaves of some hosta varieties develop a more intense color. Hostas should receive waterings every three or four days, totaling 1 to 1 1/2 inches of water per week.

Light

Hostas grow in shade, but they do best with at least a little morning sun. If the hosta was planted beneath a tree, removing some of the tree's branches will allow dappled sunlight to reach the plant. Afternoon sun is usually too hot for most hostas. During the afternoon, provide protection from the sun to prevent plant stress and dried-out soil.

Fertilizer

An application of starter fertilizer can give transplanted hostas the boost they need to grow again. Hostas transplanted in the summer, however, should not receive excess fertilizer, as it may cause delayed hardening off. Late summer fertilizing can encourage the hosta to put out tender new growth that will die if winter temperatures dip below 28 degrees. A phosphorus fertilizer helps develop the roots of transplanted hostas. The fertilizer should ideally be applied in the spring, after the danger of frost has passed. Too much nitrogen-rich fertilizer causes leaves to wilt and lose their variegated pattern. Give hostas an application of balanced fertilizer, such as 10-10-10, three or four times per year.

Mulch

A 2-inch layer of mulch will protect transplanted hostas during the winter as they recover and grow healthy root systems. Applying a 1-inch layer of mulch in early summer helps cut down on weeds, lessens soil compaction and reduces the need for watering. It also deters crawling pests, such as slugs and snails. Shredded leaves, wood chips and pine straw make good mulches.
